Sound Card Controlled Cold Cathode review

Cold cathode lights have become an increasingly popular addition that enthusiasts have turned to in order to give their cases a distinctive flair. However, the always-on nature of many cold cathode lights can get boring after a while. Consequently, kits have been created that make the light change its illumination according to the sounds playing on your computer. Ryan Wilhelm, known to forumgoers as "Spiv," had the opportunity to review an innovative Sound Card Controlled Cold Cathode from Directron.

What separates Directron's model from other sound-activated lights is that it receives its sound input directly from the sound card. Most sound-sensitive lights use a built-in microphone for input; however, there are several drawbacks to using a microphone for input. First, the light not only reacts the sound coming from your computer, but also from any other extraneous environmental sounds. The other problem is that if you use headphones, the microphone will not pick up the signal. With a direct input from the sound card, the light is sensitive only to what comes from your sound card.
